🚨New preprint doi.org/10.64898/2026.06.07.730682. We show that zebrafish larvae exhibit complex, internally generated, spontaneous behavioral patterns in the absence of stimuli. These dynamics can be described by a simple Markov process with transition probabilities that change over time.

Yet another #zebrafish genome update: We just updated our ZebrafishGenomics public datahub for the UCSC browser (available all the way at the bottom here: genome.ucsc.edu/cgi-bin/hgHu...). We added several useful tracks including:

Finally out in @natneuro.nature.com! A forgotten memory isn't always gone. We show that forgotten memories persist as silent memory traces, can be recovered by reminders, and can even be reconstructed into false memories. Excited to finally share this work! www.nature.com/articles/s41...

New paper out: www.cell.com/iscience/ful... Congratulations to our former PhD student @maxcapelle.bsky.social whose work reveals that the switch in light preference across zebrafish development is driven by a reweighting of three parallel visual processing pathways. Check out a short summary below!

We are proud to have @maxcapelle.bsky.social's paper out on bioRxiv! He found that phototactic behavior in #zebrafish switches during #ontogeny🐟🔆 Through elegant behavioral dissections, he identifies the navigational strategies related to this transition. www.biorxiv.org/content/10.1... Thread 👇

Might cerebellar disinhibition underlie Restless Legs Syndrome symptoms? Will Joo found that loss of the RLS-associated gene meis1b perturbs locomotion in zebrafish by disinhibiting cerebellar output. www.sciencedirect.com/science/arti...

Congratulations! This was long in the making and the resulting data is quite beautiful. Definitely worth a read!
